Breach Summary
In 2021, a dataset attributed to IndiaMART, roughly 41 million records here (reported 38M+ with about 20 million unique emails), was advertised on a hacking forum. It contained names, email addresses, phone numbers and physical addresses but no passwords. Because IndiaMART supplier contact data is largely public-by-design, this is best characterized as scraping/collection rather than a confirmed intrusion; whether a vulnerability was also exploited is unclear.

About IndiaMART
IndiaMART is India's largest online B2B marketplace, founded in 1996 and headquartered in Noida, connecting buyers with suppliers across a vast range of product categories. Publicly listed, it hosts millions of registered suppliers and buyers who publish business listings, contact details and product catalogs to transact with one another.
Why They Hold Your Data
As a supplier-buyer marketplace, IndiaMART holds business-contact records for its registered suppliers and buyers, including names, email addresses, phone numbers and business/physical addresses. Much of this contact data is published by design on public seller profiles to enable inquiries, which shapes how the exposure should be read.
Recent Developments
In August 2021 a threat actor advertised an IndiaMART database of 38M+ records on a cybercrime forum; it remains unclear whether the data was scraped from public listings or obtained via a vulnerability. IndiaMART continues to operate as a listed market leader.

Breach Impact
The aggregation of tens of millions of business contacts into a single downloadable dataset lowers the effort for mass B2B spam, phishing and fraudulent-supplier schemes, even though individual fields were largely public. It raised questions about IndiaMART's exposure of member data, though no passwords or financial data were involved.
Exploitation & Downstream Threats
• SIM swap attacks where phone numbers are present | • Targeted phishing campaigns using exposed email addresses | • Doxxing risk from physical address exposure
Principal Risk Advisory
What this means for a principal
A consumer-service breach: contact and account data supports phishing, account takeover and profile enrichment. For a high-profile principal this is targeting-grade, not merely identity-theft-grade: the combination lets an adversary locate, impersonate, or pressure the principal with little additional work.
What You Should Do
- Treat the home address as exposed: review mail and package handling and physical-security routines, and brief household staff to verify unusual requests.
- Guard against SIM-swap and vishing: add a carrier port-out PIN and verify any 'support' calls independently.
- Do not use unofficial 'am I affected' lookups; several are themselves harvesting operations.
How ObscureIQ Can Help
- Corpus confirmation: determine whether and where the principal (plus household and staff) appear in this dataset and which specific fields are exposed for them.
- Exposure mapping and footprint neutralization: cross-reference against broker-available data and suppress still-removable elements, prioritizing address and phone, since this record re-seeds broker networks.
- ThreatWatch tuned to this incident's identifiers and misuse pattern (impersonation and targeting patterns, not generic credential monitoring).
